Configuring Link Aggregation

Refer to Figure 28-10 for the definitions that follow.

MLAG switches: MLAG aware switches running Dell Networking OS switch 

firmware. No more than two MLAG aware switches can pair to form one end 

of the LAG. Stacked switches do not support MLAGs. In the above figure, 

SW1 and SW2 are MLAG peer switches. These two switches form a single 

logical end point for the MLAG from the perspective of switch A.
MLAG interfaces: MLAG functionality is a property of port-channels. Port-

channels configured as MLAGs are called MLAG interfaces. Administrators 

can configure multiple instances of MLAG interfaces on the peer MLAG 

switches. Port-channel limitations and capabilities like min-links and 

maximum number of ports supported per LAG also apply to MLAG 

interfaces.
